Kerupuk and kemplang industries produce at least 65 liters of waste cooking oil per production. One form of the application of science and technology in the field of new and renewable energy can be done in processing the waste oil from industrial production through the conversion process into one of the environmental friendly alternative fuels, biodiesel. Biodiesel production process can be carried out by various methods, such as utilizing induction heating technology. This technology has non-contact properties that do not interfere with the reactions that occur because of its application, which produces heat from the workpiece. This study uses waste cooking oil as raw material with variations in the molar ratios 1:3, 1:4, 1:5, 1:6, and 1:7. The analysis showed that the maximum biodiesel production was used of 1: 7 molar ratio with 86.95% yield, 0.86 gr/cm3 of density, 5.73 cSt of viscosity, 190oC of flash point, and 0.44 mg-KOH/gr of acid number. The using this ratio produces maximum yield and following SNI.

The limitations of fossil fuel support on fulfillment of energy need in a sustainable and environment friendly fashion has drove society to efforts of finding and developing fresh and renewably resources. Biodiesel is one the renewable energy resource and shows environment friendly property, consist of alkyl of fatty acids monoester originated from vegetable oil or animal fat.One of important steps in biodiesel production is separation of glycerin from product. Electrostatic method has been proved in accelerating saturation of glycerin. However, several aspects still need a careful assessment to acquire biodiesel production process with standard quality assigned. In this work, we designed an electrostatic separator of biodiesel from glycerin using waste cooking oil feed. The prototype was tested in several different voltages 12 Vdc, 20 Vdc, 30 Vdc and 33.5 Vdc. The result shows the highest voltage obtained is 33.5 Vdc, separation time 2 minutes 10 seconds having viscosity, water content and density i.e. 7.2139 cSt, 0.0321% and 0.85 g/mL respectively whereas flash point increase to 1917 C. The data confirmed that the product fulfills required standard value fordensity, water content and flash point.

Small and medium businesses (SMEs) have developed rapidly in Indonesia, especially for the food sector. One of the most productive UKM in Prabumulih city is UKM Melati which produces pineapple chips from pineapple which is a regional superior product from Prabumulih city. To get dried and tasty pineapple chips, frying is done by using a vacuum frying method that requires a lot of cooking oil. The results of vacuum drying frying will produce used browning frying oil or used cooking oil and cannot be reused if the characteristics of used cooking oil exceed the standard. For this reason, an analysis is needed to determine the characteristics of used cooking oil from the results of the production of pineapple chip vacuum vacuum frying methods. From the results of the analysis that has been carried out on filtered used cooking oil, the value of free fatty acid (FFA) is 4.9% (maximum requirement 0.3%) and peroxide value 1.8 Meq/kg. Thus, used cooking oil cannot be used anymore for frying.

Application of technology to the community program is intended to help solve the problem of clean water that exists in SMP Negeri 3 and SMP PPT in Kenten Laut, Talang Kelapa District, Banyuasin. Before this program was held, the condition of the water used by the school was quite apprehensive because it only utilized the water available in the swamps and rivers around the school. The available water has poor characteristics, especially containing turbidity and iron that have not yet met the standard. Considering such conditions, we apply the results of our research to be able to assist these two schools in providing clean water through the Application of Water Treatment Plants. This installation is quite simple and easy to operate, where the installation consists of several main process such as netralitation, coagulation, floculation, sedimentation, and stage of filtration. The quality of clean water product from the installation has fulfill the requirements as a source of clean water based on Permenkes RI No.492 / Menkes / Per / IV / 2010.

Characterization of Palm Shell-Derived Bio-Oil Through Pyrolysis Leila Utarina; Rusdianasari Rusdianasari; Leila Kalsum

Lignocellulosic biomass is a renewable resource used to produce energy, fuels, and chemicals. This study aimed to determine the effect of pyrolysis temperature on product yield and product characterization of bio-oil. In this study, palm shells were selected and prepared as raw materials for bio-oil production. Palm shells were first soaked in 10% HCl and then pyrolyzed at temperatures of 300 oC, 350 oC, 400 oC, and 450 oC in a fixed bed reactor. Afterward, the reactor will emit smoke which later will condense into bio-oil. The experimental results show that a temperature of 450 oC will be a better choice for higher bio-oil yields (44.59%). The characteristics of the bio-oil obtained are density (905 – 1015.17 kg/m3), Kinematic Viscosity (1.21 – 1.5 mm2/s), and flash point (60 – 68.7 oC).

Peat water is surface water or ground water which is found abundantly in tidal, swampy and lowland areas. It has a reddish-brown color, with an acerbic taste (high acidity), and has a high organic content. Peat water can be treated using the adsorption method. Adsorption is a physical phenomenon in which the molecules of the adsorbed material are attracted to a solid surface, which acts as an adsorbent. In this study, the authors used the adsorption method to reduce the color concentration of peat water using activated chicken bones powder as an adsorbent and observing the changes that occur when mass of powder to the amount of 0.1, 0.2, 0.3, 0.4, 0.5, 1.0, 1.5 and 2.0 grams were added to 50 ml of peat water with contact time that varied from 20, 30, 40, 50 and 60 minutes. From this study, we conclude that the optimum yield was obtained when the mass and contact time were at 0.5 grams and 40 minutes, which yield a percentage of reduction of 95.59%, wherein the initial color concentration of peat water at 337.816 was reduced to 14.89 Pt-Co, which is in line with the standard color for clean water as specified in a Regulation by the Minister of Health of the Republic of Indonesia No. 492/MENKES/PER/IV/2010, which state the standard color for clean water is 15 Pt-Co.
